Years ago I used to send my stuff out for developing, and the lab I used went w/ T max developer. My negs always looked very nice.

Now I do my own stuff, shoot mostly Tri-X, and the only developers I have personal experience with are Acufine, Rodinal and D76. They all work great, it just depends on what look you're after. I'm always the weak link in the development chain, not the developer, which is why I nearly always use D76. Pretty fool proof.
